html – d性项目的等高儿童

概述我在创建一个flexbox响应网格时遇到了问题,并希望有人可以指出我正确的方向. 我希望所有的.block div都是相同的高度,而.bottom div绝对位于底部.这实际上是在当前的解决方案中工作,但是当h2标题太长并且达到2行时,我希望该行的所有h2标题都是相同的高度. 这有可能吗？ 我做了一个Codepen来说明问题： http://codepen.io/kenvdbroek/pen/eZ 我在创建一个flexBox响应网格时遇到了问题,并希望有人可以指出我正确的方向.

这有可能吗？

解决方法 一般来说,这对于flexBox或CSS是不可能的.

flex容器的初始设置是align-items：stretch.这会导致d性项目扩展到cross axis的全长.这就是所谓的“d性相等高度列”.

以下是一些要记住的注意事项：

>等高列仅适用于Flex容器的子项.换句话说,flex项必须具有相同的父项.否则,等高特征不适用.

你的问题：

I want all the h2 headings of the row to be the same height. Is this possible in some way?

不是用CSS.因为h2存在于不同的容器中,它们不是兄弟姐妹(它们更像堂兄弟),所以不同的高度不适用.
> flexBox中的等高柱仅适用于一条柔性线.通过包装创建的其他线上的项目建立自己的相等高度线.这意味着equal height columns do not work in a multi-line flex container.
> align-self属性可用于单个d性项目以覆盖对齐项目,这可能会破坏相等高度的特征.
>通过在d性项目上指定高度(例如,高度：300px),将覆盖该项目的align-items和align-self,并忽略相等的高度设置.
>这篇文章重点介绍一个具有flex-direction：row的容器.如果容器是flex-direction：column,则相等的高度变为相等的宽度.这是一个详细的评论：Make flex items take content width,not width of parent container
